Yes, jws had to pay upfront. When the Jimmy Swaggart count case was decided that people could not charge for the publications, the WTS suddenly did not charge its members, and for jws and public it was a donation to the Watchtower Society. And at one time pioneers were given a reduced for literature, including subscriptions to be delivered magazines.
"As a publishing company, Watchtower amassed considerable wealth from the sale of literature from the 1800's to the 1990s. There was no need to resort to the same collection efforts typical of other religious groups. This changed in the 1990 with a tax ruling against Jimmy Swaggart. (See the section regarding Jimmy Swaggart in the article Political Involvement) The United States Supreme Court determined despite religious not-for-profit status, Swaggart was liable for tax on the sale of religious material. The sale of Watchtower publications fell under this ruling. Watchtower decided that rather than pay tax on the money it was receiving from the sale of Watchtower literature, it would be better to direct Jehovah's Witnesses to start asking for donations from people who accepted Watchtower journals in the house to house ministry work. This led to a decline in income.
During this same period, the global publishing industry was experiencing a decline in revenue and profits due to the mainstream launch of the internet in 1995. This further exacerbated the revenue declines Watchtower was experiencing from no longer being able to sell its books and magazines.
Watchtower did not need to pass a collection plate whilst it was making money from selling books. When this income stream started to dry up, Watchtower was forced to look to other sources of income, and in the twenty-first century there has been a noticeable shift in two areas, more open requests for donations and changes in the ownership of Kingdom Halls." https://www.jwfacts.com/watchtower/donations-money-solicitation.php
